When I was farming, my tractor operators were given an order in a way that could not be misunderstood: IF SOMETHING LOOKS, ACTS, SMELLS WRONG, TURN OFF THE ENGINE IMMEDIATELY IF NOT SOONER. I always praised them for being alert, if it turned out to be nothing. Their ears were a little charred around the edges, if they ignored something. This just comes back again to my friend Jon's saying: "If you gonna be dumb, you gotta be tuff. " It jes gits mo expensiver ifn ya thinks it will jes go 'way. Mark
